Those bird shots are shot using 500D and 55-250 IS. I want a 70-200L but I think I'll stay with my current lens lineup. I can't just buy lens. My wife will certainly kick me out of our house. Kidding aside, I'm targeting a 17-40L lens next. Hopefully I'll get them early next year. After that hopefully it's a full frame finally. I'm not in a hurry to buy since I'm still learning and it takes me a lot of time to save.
